In 1975, Summer approached Moroder with an idea for a song she and Bellotte were working on for another singer. She had come up with the lyric "love to love you, baby". Moroder was interested in developing the new sound that was becoming popular and used Summer's lyric to develop the song. Moroder persuaded Summer to record what was to be a demo track for another performer. She later said that she had thought of how the song might sound if Marilyn Monroe had sung it and began cooing the lyrics. To get into the mood of recording the song, she requested Moroder turn off the lights while they sat on a sofa with him inducing her moans and groans. After hearing playback of the song, Moroder felt Summer's version should actually be released. Although some radio stations refused to play it due to its suggestive style, "Love to Love You" found chart success in several European countries, and made the Top 5 in the United Kingdom.
The song was then sent to Casablanca Records president Neil Bogart in hopes of getting an American release. Bogart informed Summer and Moroder he would release the song (now called "Love to Love You Baby") but requested that Moroder produce a longer version for discothèques. Moroder, Bellotte, and Summer returned with a 17 minute version and Casablanca signed Summer and released the single in November 1975. Here it is below.
